1 This invention-"relates to an improvement jin 'safety"mechanisms for bolt-action firearms andparticularly to that class of safety mechanisms -which. are automatically -jbrought intoand out of play by the movement 0fthe=bolt.'

i The object of thisinvention is to provide Jasim'ple'and reliable mechanism of the'class described, constructed with particular ref- 131131106130 preventing the firing-pin from be- 111 than its closed p'osition v A further "object of my invention is to addition to its main function, also act as a functioning thereof.

fvide a 'lsafety mechanism which will also act asia yielding detent for holding the boltin itsc'losed position.

i A still further object of my invention "is geffectually prevent the bolt from being operigger has been released. j .1 .lVith these objects in view, my invention V con'sistsin a safety mechanism characterized by' its provision with a movable guard-mem- ,i whichis'automatically moved into its 1lease"o'fftheffiring-pin when the bolt is unlocked, and" automatically moved into itsretired' position whenthe bolt 'is moved into 1 its locked position. v p

My-invention further consists in a safety i mechanism characterized as above and hav- {ing certain other details of construction and fdescribed and particularly. recited in the m a. ,1.

The' aforesaid bolt-handle while virtually constituting apart of the bolt 13, I

is permitted a limited oscillating movement with respect thereto, by providing its" inner 7 end with an annular ring-16 which embraces the reduced rear end 17 of the bolt and is held in place thereon by a collar 18 slipped over the extreme rearjend "of the reducedv portion 17 "of the b'olt,'-'where it is, in turn, secured in place by "a transverserpin 19, all

as clearly shown in Fig. 2., p Centrally within the hollow bolt 13is the usual firmg-pin 20, which is provided with which is engaged by-the rear face ofa searlug 22 forming a part'of a sear 23 which functions 1n the usual manner to releasably which intersects the longitudinal bore :11 aforesaid, and is urged by a helical spring,

'26 so as to engage the searflu 22 with the cocking-shoulder 21 of the fir ng-pin; The to rear end of the sear 23 is also formed with a"rearwardly-opclung notch 27 for the reception of. the;forwardend of a. forward1y .J projecting, actuating-finger'28 forming a ,partof a trigger'29 which 'is hung in the "aforesaid passage 25 upon'a transverse-pin The parts above described in substance constituteusual featuresof bolt-action firearms and *in themselves. are not herein claimed as novel.

For the purpose of preventing the firing-h pin 20 from being released -'by thesear- 23,

p whenithe bolt-handle is in its unlocked'posi- '4 tion as shown in Fig. 4, I provide the bottomof the receiverlO. with a vertical passage 31 which extends upward therethrough and through a bolt-stop segment 32 tointersect the bore :11 aforesaid. This vertical passage receives a hollow cylindrical} guard-- plunger-33 formed with an axially-arranged 5 spring-chamber and provided at its outer end with an annular overhanging stopflange, 35, which latter serves to limit the upward movement of theplunger 33Hunder the upward urge of a helical spring 36 which of j the base of the impinges at its outer end against the' upper V ifaceofa stop-finger 37which projects reap ward from the trigger 29' QfOICSZLlCL. Thespring 36 just mentioned serves the "dualv purpose of urging the trigger 29 forward and of urging the guard-plunger 33 upward into. its retired position, in which posltion its rounded'upper end 88 enters laconic-a1 vpocket 39 formed in the outer periphery the bolt-handle ring 16 aforesaid.

effect of permitting the firing-pin to snapforwardand strike the cartridge 4Q n the:

chamber of the gunebarrel. This rearward .movement of the trigger as just described,

will be limited by the engagement ofthe rearwardly-projecting. stop-finger. 37 with. the flanged'outer endfof the guard-plunger 33. ,The bolt-liandlew is'now swungup wardinto the position shown in Fig. 4, so

as to .disengage, it from the-locking-notch -l4, after which the bolt is Jdrawnrearward by means of the said handle, for extracting the cartridge just fired .and preparatoryto described, causes the sloping walls of the conical pocket 39 tocam the guard-plunger 33 downward intolthe positionin which it is indicated by broken lines in Figsf2 and 3 and by full linesrin FigQA; As thus positioned the plunger Will p'reventthe trigger from bein vJulled to"actuate the sear for" "releasing the firlng-p mjshoulc'l the'latterhe in its coekedpositiomas will be shortly described; After tl'ie'insertion of anew cartridge, the bolt is moved forward in the bore 11 by rneans of handle 15' with theei'fect ber of the un-barrel and of co ofinserting anew cartridge into the chain.- clnng'the 'tirlug-p n in theusual manner.

firing-pin cocke d as' describechthe firearm would now (with' the bolt as yet unlocked): befcapable of, being discharged with poten; tiallyfdang'erous results; were it not jo'r the. fact that.theguard-plunger 33 is, at this f With the new cartridgein place and the:

time, in position to pre,vent this from taking place. When, however, the bolt-handle is swung downward into the locking-notch '14,,

the firearm is thus rendered safe for dis- "charge." Coincident with the locking-of the" bolt, the pocket 39 is brought intoregistration-with'the upper end of thc-guztrd-plunger,

which is' noavmoved by the spring 36 into its retired position, whereby the trigger is re- {lieved of constraint; and maybe pulled iforJS effecting the releaseoftheffiring-pin through v the medium of the sear 23L It is .to' be noted that whenithe triggerisf pulled for discharging the firearm; the stop finger 37 of the trigger wlllfengage the under-:lace of the guard-plunger v33 with the eilect'of crowding-bhe'same'upwardintothe pocket 39 and effectively preventing the bolt from being prematurely unlocked-jThebolt,

can only, be unlofcked after the backward draft upon the trigger has been-relieved;
